Question regarding the NEX-7 with the Zeiss Biogon 25/2.8. Anyone know if the magenta color cast shows up in the corners with this lens?

There's also the Rokkor version of this lens, which is cheap, and the later versions are supposedly better than the Elmarit.
Leica continued production after Minolta dropped the lens in favor of the Maxxum AF, so the later version would be the E60 Leica R, which picks up improvements in the corners. It only matters if you're shooting it on a full-frame, so for the NEX, the Minolta would be great choice.
The Pen-F 25/2.8 is a character machine. Very fun walk around lens (it weighs almost nothing and extends just a bit longer than, say, an M-Summicron 50 would). Very old-school but with strong contrast and nice enough colors, if not entirely accurate.
The Oly 24/2 shows a little BD up close as well as field curvature, but over 5M, it's well-corrected and nearly impossible to get to flare. The color pallet is true but the contrast is low and balance fairly flat. It's fantastic for B&W. Color will take more effort in post. CA is its biggest problem, but it's so easily corrected in software now, it hardly seems worth mentioning. f/4-8 is the lens' sweet spot on the aperture, but it's sharp enough in the center wide open with a minor improvement at f/2.8.
The Canon FDn 24/2 could basically be a ditto (roughly the same size and weight, same filter size, same performance issues) but it does have a couple of unique attributes. Colors are Canon, so watch your reds and flare is not only possible but relatively easy.
The Komine 24/2 is basically a soft focus lens up to f/4, when it starts to get sharp. Add up the problems of the Oly and the FD, multiply them to the power of two, and be prepared to shoot a lot at f/8. Cheap, though. Very cheap and actually pretty well built. Available in a variety of mounts. The one I had was OM, I believe. One of the Vivitars is a rebrand of this lens.
I'd like to hear about the Nikon 24/2, if anyone has any experience with that lens.

Unfortunately, yes, strong magenta cast. But, in that focal length, there is one thing you must do, Bob. DO NOT try the Leica Elmar 24mm. First, it's grossly overpriced. Second, it is slow, at f:3.8. Third, there is a magenta cast. so, in summary, DO NOT try it. You just might love it, and none of us want to do that to you.

was thinking of getting Zeiss Biogon 25/2.8 too.. anyone has pic of how bad the magenta color cast is?
Errz, the magenta cast can be cured with CornerFix. So how bad it is does not matter that much IMHO, because, either one is prepapred to use Cornerfix (or another similar system, such as Capture One), and then it is OK, or one is not, and the cast is unacceptable. Just my $.02

Both companies made improvements. My understanding is the more recent Leica versions replaced the glass types but retained the essential lens design from when the two companies collaborated (9 elements, 7 groups), while the latest Rokkor 24 tweaked the design (8 elements, 8 groups). My sense of which of all these versions is best is based on hearsay, but I think we can agree that all of these versions of this lens are very good, though not as good as the best Leica R lenses.
It had better be as sharp as the Sigma, or it will be a tough sell.
Even if it's a little less sharp than the Sigma, I'd still be interested for the extra stop. If it has OSS, and is smaller than the Sigma 30, I'd be very interested.
